Android通过http协议POST传输方式

Android通过http协议POST传输方式如下：

方式一：HttpPost（import org.apache.http.client.methods.HttpPost）

代码如下：

private Button button1,button2,button3;

private TextView textView1;

button1.setOnClickListener(new Button.OnClickListener(){

@Override

public void onClick(View arg0) {

// TODO Auto-generated method stub

//URLַ

// String uriAPI = "http://www.dubblogs.cc:8751/Android/Test/API/Post/index.php";

String uriAPI = "http://172.20.0.206:8082//TestServelt/login.do";

/*建立HTTP Post连线*/

HttpPost httpRequest =new HttpPost(uriAPI);

//Post运作传送变数必须用NameValuePair[]阵列储存

//传参数 服务端获取的方法为request.getParameter("name")

List <NameValuePair> params=new ArrayList<NameValuePair>();

params.add(new BasicNameValuePair("name","this is post"));

try{





//发出HTTP request

httpRequest.setEntity(new UrlEncodedFormEntity(params,HTTP.UTF_8));

//取得HTTP response

HttpResponse httpResponse=new DefaultHttpClient().execute(httpRequest);



//若状态码为200 ok

if(httpResponse.getStatusLine().getStatusCode()==200){

//取出回应字串

String strResult=EntityUtils.toString(httpResponse.getEntity());

textView1.setText(strResult);

}else{

textView1.setText("Error Response"+httpResponse.getStatusLine().toString());

}

}catch(ClientProtocolException e){

textView1.setText(e.getMessage().toString());

e.printStackTrace();

} catch (UnsupportedEncodingException e) {

textView1.setText(e.getMessage().toString());

e.printStackTrace();

} catch (IOException e) {

textView1.setText(e.getMessage().toString());

e.printStackTrace();

}

}



});

方式二：HttpURLConnection、URL(import java.net.HttpURLConnection;import java.net.URL;import java.net.URLEncoder;)

private void httpUrlConnection(){

try{

String pathUrl = "http://172.20.0.206:8082/TestServelt/login.do";

//建立连接

URL url=new URL(pathUrl);

HttpURLConnection httpConn=(HttpURLConnection)url.openConnection();



////设置连接属性

httpConn.setDoOutput(true);//使用 URL 连接进行输出

httpConn.setDoInput(true);//使用 URL 连接进行输入

httpConn.setUseCaches(false);//忽略缓存

httpConn.setRequestMethod("POST");//设置URL请求方法

String requestString = "客服端要以以流方式发送到服务端的数据...";



//设置请求属性

//获得数据字节数据，请求数据流的编码，必须和下面服务器端处理请求流的编码一致

byte[] requestStringBytes = requestString.getBytes(ENCODING_UTF_8);

httpConn.setRequestProperty("Content-length", "" + requestStringBytes.length);

httpConn.setRequestProperty("Content-Type", "application/octet-stream");

httpConn.setRequestProperty("Connection", "Keep-Alive");// 维持长连接

httpConn.setRequestProperty("Charset", "UTF-8");

//

String name=URLEncoder.encode("黄武艺","utf-8");

httpConn.setRequestProperty("NAME", name);



//建立输出流，并写入数据

OutputStream outputStream = httpConn.getOutputStream();

outputStream.write(requestStringBytes);

outputStream.close();

//获得响应状态

int responseCode = httpConn.getResponseCode();

if(HttpURLConnection.HTTP_OK == responseCode){//连接成功



//当正确响应时处理数据

StringBuffer sb = new StringBuffer();

String readLine;

BufferedReader responseReader;

//处理响应流，必须与服务器响应流输出的编码一致

responseReader = new BufferedReader(new InputStreamReader(httpConn.getInputStream(), ENCODING_UTF_8));

while ((readLine = responseReader.readLine()) != null) {

sb.append(readLine).append("\n");

}

responseReader.close();

tv.setText(sb.toString());

}

}catch(Exception ex){

ex.printStackTrace();

}

}
